The Issue:
When we have more than 2 onetime items where the second has a discount, the before_discount_amount_total for the recurrence is incorrectly calculated because it didn't account for the first item's amount (which had no discount).
The Fix:
Changed the logic to initialise existingRecurrenceBeforeDiscountAmountTotal with the recurrence current amount_total (minus the item being added) when it's undefined, ensuring all previously added items are included in the before-discount calculation, even if they didn't have discounts themselves.
